Made by the non-wood material ABACA (Manila hemp) and wood-pulp based on a forestation project. The Cafec ABACA filter paper is eco-friendly, has good air and liquid permeability, toughness, and elasticity. Cafec produces this filter paper using a special technique to incorporate a 2-side crepe feature onto paper. This allows a smooth water flow and less chances of blockage during coffee brewing. Perfect for use with any trapezoid/flat bottom dripper e.g. Kalita 102/103, Clever Dripper, Bee House Dripper & Bonavita Dripper and Moccamaster. Cafec Abaca Trapezoid Filter Papers Features Eco-friendly - Made with wood-free and sustainable Abaca fibres. Faster water flow - The specialized 2-crepe method improves the filter paper’s permeability. Better water flow-control - Only your pouring technique and coffee grind size affect how quickly water passes through.
